不同采购模式下的配套部件采购策略

Procurement Strategy of Matching Components in Different Procurement Modes

采购是制造企业控制成本,增强企业竞争力的关键环节。将不同的采购模式纳入到制造商配套部件的采购行为分析框架中,构建了采购策略模型,得到了部分信息、无有效信息和完全信息下的最优采购策略,并探讨了更新信息质量对集中采购策略的影响,证明高信息质量并不总能够激励制造商采用分散采购模式。最后,通过算例对信息数量和信息质量的敏感性进行了分析。

Procurement is the key for manufacturers to control cost and enhance their competitiveness.In this paper,different procurement modes were incorporated into the analysis framework of manufacturers'behavior about matching components procurement.The model of procurement strategy was constructed and the optimal strategy was obtained under the condition that there is some information,there is no valid information and there is complete information.The influence of information quality on the centralized procurement strategy was discussed. It was proved that high quality information does not always motivate manufacturers to use decentralized procurement.Finally,the sensitivity of the quantity and quality of information were analyzed by simulative data.
